Abstract

A rotor (5) particularly for mixing machines of internal type (1) for elastomers and plastomers, equipped with at least one pair of blades (6) each projecting from the cylindrical hub of rotor (5) starting from flank (5c) of the rotor and set helically thereon, in which at least one of such blades (6) has at least one split delimited by two blade sections (6a, 6'a; 6b, 6'b; 8a, 8'a; 8b, 8'b; 10a, 10'a) located parallel to one another, one section (6a, 6b, 8a, 8b, 10a) having one of its ends located at flank (5c) of rotor (5) and at least one section (6'a, 6'b, 8'a, 8'b, 10'a) being separated from the previous one or located on the same helix or on parallel helices to create at least one passage opening (7) capable of bringing about diversion of the flow of material during mixing. <IMAGE>
